In the ordinary fulledfabrics with rectangularly crossing warp and weftthreads, the warpthreads extend in the lon itudinal direction and theweft threads in t e transverse direction of the fabric. The same is thecase in garments and other articles made of. such fabrics. If thisvfabric or articles made thereof are submitted to tensile stresses in thelongitudinal direction, it will only be the warp threads which willoppose resistance to the stresses, while the weftthreads i'emain`entirelinactive. It will be inverse if the fabric 1s placed under stress in thetransverse direction. 'I The invention has for its object to rovide afulled woven `fabric in whichA t e recL tangularly `crossing warp-andweft threads extend diagonally with relation to the edges of the fabric.

In the accompanyin 2 illustrate, by way 0% manufacturing'a' 'fabricaccording to the present invention. I

In a manner known per se, the fabric is drawing Figs. 1 and 25 firstwoven in the form of a tube a,.Fig. 1,

yin which the warp threads extend longitudi nally and the weft threadstransversely. The tube thus formed is then cut up alonga helical line binto a simple web of fabric c,

shown in.Fig. 2. As will be seen from the last-said figure, the warp andweft threads while crossing rectangularly extend diago-I nally withrelation to theedges of the fabric. A fulled'fabric according to thepresent invention possesses numerous advantages over the ordinary"fulled fabrics vin which the warp threads extend in the longitudinal andthe weft threads in the transverse direction. i The present fabric isvery ductile both in the 40 longitudinal and transverse direction, i. e.in the directions in which garments made of the -fabric are submitted totensile stress.

' Besides, in making garments, covers, etc. of the fabric'the edges neednot be' provided with seams but 'they can remain open even if the fabricis made of cheap raw materials such as, for instance, of sho dy. Sincethe V warp and weft threads-form anA acute angle edges.

example, a mode of valon with the fabric edges so that no thread extendsparalleli-y of the same, the felting of the threads obtained by thefulling operation keeps the threads together in such a manner as torender impossible a feazing of the greater tensile strength than the oldfabrics because any longitudinal and tarnsverse stresses are taken up bythe warp and weft threads inlcommon. Therefore, raw materials ofcomparatively minor quality may be used for manufacturing a cloth-ofdefinite strength.

As the fabric is lyieldable in two directions..

garments made from the saine will fit better than garments of theordinary fabric.

Owing to thegreater strength or resistibility of the fabric in thedirections in which the tensile stresses are mostly exerted, it can 'Thepresent fabric further has al be made of less threads per unit of areathan 'the garment cloth used hitherto.' Thereby, theI cloth4 becomescheaper and' lighter, while nevertheless a high density and insulativeproperty may be imparted to it by an lefficient raising and fullingoperation.

Having thus described my invention, what I claim as new and desirek toSecure by Letters-Patent, is I 1. Al'nethod of producing a fulledwoven'. fabric, consisting in weaving the fabric in tubular form,cutting said fabric tube a helical line to provide a web .of fabric inwhich the rectangular crossing warp and weft threads extend diagonallywith relation to the longitudinal edges ofthe fabric and iinishin thefabric to* full the same whereby in t e ful'ling operation the and weftthreads are equallygengaged warp Aby. t e finishing instruments.'

'2.l Asa new product, a fulled woven fabric in which the crossing warpand weft threadsv extend diagonally'to the respective edges ofthe-fabric.

. In testimony whereof Lhave signed my name tothis specification. a
